OPUG

When looking for an Aerial Dielectric Self Supporting fiber optic cable, whether your application needs a long or short span, requires increased carrying capacity, harsh environments or custom-made solutions that shall fulfill your expectations, you should be looking for OPTIVINE. Our typical ADSS construction consist in a central FRP, surrounded by jelly filled loose tubes, containing optical fibers, water blocking materials and UV resistant outer sheath. The cable is strong enough to support itself between poles without using conductive metal elements, a feature important when installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors.

Micro-Module Multi-Purpose cable was designed for FTTH and long-haul networks, for aerial or duct installations, being compact, lightweight and easy to handle. Compared with conventional cables it shows several features that bring benefits inducing significant time and cost savings during laying or jointing process. This special indoor/outdoor cable contains bend-insensitive fibers, protected by easy strippable micro-tubes. Two constructive solutions are common, MOD6 and MOD12, representing 6 or 12 fibers per tube. Other requirements/solutions can be offered upon request.

Underground fiber optic cables that are designed for duct or direct burial installation, fully dielectric cable or with metallic elements for increasedmechanical protection. Due to our new technology, the cables show good flexibility and endurance to repeated bending, excellent mechanical properties and great water blocking function. We can offer custom solutions up to 864 fibers.

MICROCABLE

OPGW

DROP

Is designed for applications where large numbers of fibers are required and space is limited, especially used in data centers and metropolitan networks. These cables are ultra-compact and lightweight, allowing an easier installation technique by which the cable is “blown” into micro ducts or plastic tubes much smaller than conventional fiber ducts or conduits.

These conductors are used in overhead power lines, smartly combining the functions of grounding and communications. Containing single-mode optical fibers with low transmission loss, OPGW allows long distance transmission at high speeds. The optical fiber itself is immune to power transmission line and lightning induction, external electrical noise and crosstalk.

It's used in the FTTH infrastructure from outdoor or indoor distribution points up to the customer’s location. Drop cables are engineered to adapt to various installation environments, including outdoor, indoor or mixed solutions. OPTIVINE offers CPR compliant drop cables with easy access to the fiber, enabling fast and comfortable installations. A wide range of constructive solutions are available.

Aluminium Conductor Steel-Reinforced is a type of high-capacity, high-strength stranded conductor, typically used as active conductor in overhead power lines. This type of conductor is suitable for medium and long span applications thanks to the high value of specific mechanical resistance and good transport capacity. To prevent the galvanic corrosion, a thin zinc coating on the wire is carried out.

Thermal Resistant Aluminum Alloy Conductor Steel Reinforced, consists of one or more layers of thermal resistant aluminium zirconium alloy (AT1) wires stranded over a central core of zinc coated steel wires. TACSR conductors features a higher current carrying capacity than traditional ACSR conductors, using the same installation technique.

Features: Improved conductivity

Better self damping property

Very low sag at high temperature

High current carrying capacity

Excellent immunity to vibration fatigue

Long term creep of aluminum does not affect final sag

Aluminum Conductor Steel Supported is suitable for operating at high temperature without loosing the mechanical properties. The final sag-tension performance is not affected by the long term creep of aluminum. This conductor is a concentric-lay stranded conductor, with one or more layers of hard drawn and annealed 1350-0 aluminum wires on a central core of steel. Under normal operating conditions, the mechanical load of ACSS is mainly derived from the steel core, as aluminum in fully annealed stage does not contribute much towards the mechanical strength.

All Aluminium Alloy Conductors, are used for primary and secondary transmission in bare overhead distribution and transmission lines. It has a good corrosion resistance, however due to the absence of steel, its resistance is lower than ACSR. In the same time AAAC offers lesser corona losses and ratio interference at EHV and can be operated with stable temperature of 85°C towards ACSR conductors which are stable up to 75°C. Since AAAC has higher strength-to-weight ratio, span can be increased up to 15% resulting in overall reduction of costs.

Wire mesh cable trays are produced from high mechanical strength steel wire. The mesh permits continuous airflow to help prevent heat buildup. This open design also prevents the build-up of dust, contaminants and bacterial proliferation and is primarily used for the support of low voltage, telecommunication and fiber optic cables. The life expectancy of a cable support system is dependent on the environment in which it is placed, therefore it is important to establish the corrosive properties of an environment to ensure that the right treatment and the right material are chosen.

Treatment typesElectro-Galvanized - electrolytically, a zinc coating is deposited on the steel. The baths used consist of acid or alkaline solutions of zinc salts. The minimum coating thickness by this method is 8µm. Such products are intended for use only in warm, dry areas with negligible pollutant levels.

Pre-Galvanised - this galvanization method is the one which is practiced before there is any fabrication done over the material. This homogeneous coating thickness on the surfaces has a value from 10µm to 20µm (70gr/m2 140gr/m2) in accordance with EN 10346. Is recommended to be used inside buildings where dry air is present.

Hot Dip Galvanised - is a coating method performed by dipping iron and steel products suitable for galvanizing into a molten zinc bath. The minimum coating thickness on the surfaces is 45µm (325gr/m2) and the average coating thickness is about 55µm (395gr/m2) in accordance with EN ISO 1461 quality standard. Usage of hotdip galvanized cable trays is suitable in any environments and it can keep its protective feature even in the heaviest atmospheric conditions.

Strings are a series of two or more tension or suspension insulators, flexibly connected by using various clamps and hardware fiings. There are four types of insulator strings: single tension string, double tension string, single suspension string, double suspension string, all of these in different configurations and heights.

Suspension Composite Insulators - are used to support a conductor of an overhead transmission line, consisting of one or a string of insulating units suspended from a pole or tower, with the conductor attached to the end.

Tension Composite Insulators - are designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical cable or conductor. They are used in overhead transmission lines, between two lengths of a conductor, to isolate them electrically from the tower while maintaining an electrical connection.

Post Composite Insulators - are used to support different equipments in a substation. These insulators are generally subjected to bending, torsion and compression forces in service. They can support the structure horizontally as well as vertically. Available for MV and HV level, these insulators with silicone rubber sheds offer significant benefits over traditional ceramics with superior insulation properties, flash-over resistance, and low weight.

*Connection type for all post and/or line post insulators is tailor-made acc to client' specifications.

Also known as Disconnector is a switching device used to isolate an element of the electrical network (HV line, transformer, portion of electrical station, etc.). It ensures network operators that the electrical circuit is de-energized and that they can proceed to maintenance or repairs, safely, without electrical risks. Visible breaking of the circuit is possible by using such a disconnector switch. These products can be operated mechanically or automatically, available with single-pole construction and three-pole construction. The disconnectors ca be equiped with earthing switch where the application requires.

* Other types of disconnectors can be tailor-made according to requirements.
